Welcome to my fun-loving blog about my journey as an ethical hacker! One of the most important things I have to learn is how devices and systems talk to each other. That’s why I’m diving into the world of CCNA Networking with David Bombal.

You might be thinking of a social media network or your contact network when you hear the word “network,” but it’s so much more than that. During a tutorial with David Bombal, we even asked Alexa, the Apple Home Assistant bot, to explain what a network was. It responded by saying that a network is a digital interconnection of telecommunication networks for sharing resources between nodes. Nodes are computing devices that use a common telecommunications technology.

So why do we need networks? The sole purpose of a network is to share resources faster and efficiently. A resource could be a file, a video, a printer, and more. It’s been an awesome journey learning about how networks have evolved over time, and how specialized devices like hubs, switches, routers, and firewalls play a role.

David Bombal also taught me that the biggest network in the world today is the internet. Pretty cool, right? And speaking of big networks, he even showed me how to share files from one laptop to another using a USB drive without a network.

We also learned about the most basic form of computer networking, which uses a copper ethernet cable, also known as an unshielded twisted pair (UTP) cable or an RJ45 connector. It can be a bit confusing, but David Bombal made it easy to understand with practical demonstrations. We also learned about network interface cards, or NICs, which is how we connect to a physical or wireless network. Each device has a unique MAC address, or Media Access Control address.

David Bombal also taught me about different types of ethernet cables, like RJ45, 10base2, and 10base5, which were used in the past. But, in today’s world, WiFi is the way to go. WiFi, or Wireless Fidelity, is a network that allows for sharing and connecting over the air. It’s so much faster and more convenient. David Bombal even showed me a practical demonstration of sharing a file from one mobile device to another wirelessly.

Overall, David Bombal’s teaching style is superb because of the practicality he brings to the subject. I’m having so much fun learning about networks and can’t wait to see what else I’ll discover on this journey. Thanks for Joining me on this journey. Happy Reading!
